摘要
[目的]研究酸浆和甜菇娘的营养成分。[方法]采用索氏提取法测定水分、灰分和粗脂肪,并用凯氏定氮法测定蛋白含量;无机元素的分析按GB/T12393-90测试方法进行;用GB 12388-90法检测脂溶性维生素,GB 12392-90法检测水溶性维生素。[结果]酸浆和甜菇娘果实与宿萼中含有丰富的无机元素,以钾、磷、钠、镁和钙的含量较高,而有害元素铅和砷等未检出;氨基酸含量丰富,种类达18种以上,其中天门冬氨酸的含量最高;此外,还含有丰富的维生素。[结论]宿萼中的无机元素、氨基酸等营养素含量高于果实,这为宿萼的合理利用提供了理论依据。
[Objective] To research the nutritional components of Physalis alkekengil var.francheti and P.pubescens L.[Method] Moisture content,ash content and crude fat content were detected by Soxhlet extraction.Protein content was detected by Kjeldahl Method.Inorganic elements were analyzed by the detection method of GB/T12393-90.Fat-soluble vitamins and water-soluble vitamins were detected by GB 12388-90 and GB 12392-90,respectively.[Result] There were abundant inorganic elements in the fruits and persistent calyx of P.alkekengi and P.pubescens.Among them,K,P,Na,Mg and Ca had relatively high contents;while Pb and As were not detected.Amino acids were abundant,which had more than 18 kinds.Among them,aspartic acid had the maximum content.Besides,there were abundant vitamins.[Conclusion] Contents of inorganic elements and amino acids in persistent calyx were higher than those in fruits,which provided theoretical basis for the rational utilization of persistent calyx.
